DIY or hire a plumber. Installation: 15 minutes or less in most instances. The Floodstop for water heaters includes a security system and auto dialer output contacts. The water shut off controller is AC with a battery back up.(No batteries included). With a full port motorized stainless steel ball valve, the FloodStop uses a brass valve assembly lined with Teflon for long wear. The water leak sensor (included) is double sided.

Installation: Connect valve to the cold water line to the water heater. Mount the control unit. Place sensor(s) on floor. Plug power supply into an un-switched outlet. Note: electricity is used only when the sensor detects water.

NOTE: DO NOT PLACE SENSOR DIRECTLY ON METAL PAN OR DAMP FLOOR. If no water is present and alarm sounds, place paper towel or cloth under sensor to "insulate" against floor dampness or metal of pan. When the paper or cloth gets wet, the sensor activates the shut-off and sounds the alarm.

How FloodStop (FS 3/4-C) Works:

The FloodStop valve installs between the water heater and its manual shutoff valve.

Water/leak sensor placement is at the water heater base.

Valve is open until water leak is detected

Water on the sensor signals the Floodstop controller which closes the valve and alarms.
